- BOTTLE-CAP rnnfnnisrnnsnn Len-n SPR ADE Be it known that I, JEREMIAHERWIN, a

citizen of .the United States, and a resident Cap Fluid Dispenser andSpreader ;and I do,

ofthe city of Chicago, in the county of Cook and State ofv lllinois,have inventedcertain newand useful Improvements in a Bottleherebydeclare that the following is a full, clear and exact description of thesame, reference. being had to the accompanying drawings, and to thenumerals ofreference marked'thereon; which form a part of thisspecification.

This invention relates more particularly to a bottle cap fluid-dispenserand spreader in which the bottle cap is adapted to pro 7 vide'thespreading surface and in which the fluid is dispensed from the bottlethrough an aperture in the cap which is closed by spring controlledmeans.

In bottle caps of this type as heretofore constructed the springscontrolling the closing of the aperture were quite complicated and ofsuch construction that they were soon deteriorated by the action of thefluid in the bottle and failed to effectually close the aperture.

It is therefore an object of this invention to provide a bottle caphaving an aperture therein which is closed by spring controlled means.

It is a further object of this invention to provide a cover for a fluidcontainer having a spring controlled aperture therein and having aportion of the cover adapted to'be used for spreading the fluid.

It is an important object of this invention to provide an aperturedcover for a container having means for closing the aperture, said meansbeing operatedby a single wire leaf spring secured within the cover.

Other and'further important objects of this invention will be apparentfrom the disclosures in the drawings and specification. The invention(in a preferred form) is illustrated in the drawings and hereinaftermore fully described.

On the drawings:

As shown on drawings i r vThe referencenumerall indicatesia con; tamerhaving an e ternal-flange Z at thetop thereof. {A cap. 3,; having anaperture 4 and a flat surfaced portion 5', is secured to the flange, 2bya clamping ring 6,.and an air-Q. tight joint is assured by the use ofa packing- 7 between the clamping ring 6 and the flange 2. The aperturea is closed-by means'of a ball 8, which is releasably held in positionin the aperture by a wire leaf spring 9 which is secured inside the cap3 and opposite the aperture by brazing or other suitable means. The leafspring 9 consists of a straight spring wire bent upwardly to form abight 10,. which serves to force the ball 8.

into the aperture 4. The side of the bight 10, which is opposite theaperture 4, is bent to conform to the casing 3, with which it is incontact. Internal projections 11 on the cap 3 serve to prevent thespring 9 from being displaced laterally. It will be seen from the aboveconstruction that the spring 9 and the ball 8 are secured only to thecap 3, a featurewhich makes possible the removal of the cap 3 withoutdisplacement of or injury to the spring or ball.

The operation is as follows:

downwardly the fluid contained there in will flow into the cap 3. [Todispense the fluid (as glue, mucilage etc.) from the bottle the ball 8is pressed against the surface on which When the topof the bottle l is.tilted spring aperture. closing means embodyi it is desired to place thefluid. This pressure on the ball8 causes it to recede into the cap 3,thus opening the aperture 4 and permitting the fluid to'escape. The fiatsurface 5 may then be used to spread the fluid evenly over the surfaceon which it is poured. As soon as the pressure is removed from the ball8 the action of the leaf spring 9 forces the ballback into the aperturethus sealingthe bottle. Due to the shape and peculiar arrangement of theleaf spring 9, the fluid does not adhere to it and interfere with itsaction. I

I am aware that numerousdetails of concap closing said bottle,"a portionof said cap being flattened to provide a plane surface oblique to theaxis ofsaid bottle and at one side thereof, an aperture in the curvedsurface of said cap, a valve for closing said aperture, aspring forholding said valve in closing position, said spring having a portionattached to the inner Wall of the cap, a portion attached to the valveand at an angle to the first named portion and a portion connecting thesaid two portions and forming acompound curve,all the portionsofisaidspring being in one plane, the flattened portion of said capbeing on r p the side of'said aperture opposite the bottle.
